Novice U6-U7
Soccer (football) training videos covering ball mastery drills (Coerver techniques), cones dribbling drills and 1v1 moves for the age group U6-U7.
Kids at this age have a very short attention span. One drill per training session is more than enough. It shouldn't be too difficult to make a game out of it.
It is important though that they practise the drills with both feet. The sooner they get used to practise with the non-preferred foot, the easier it will be at a later age.
